.To alt whomvlt may concern.-

Bet known that we, JAMES RAMSEY SPEER, residing at Pittsburg, and HENRY A. OTTO, residing at4 Alleghen in the county of Alleghen andState of ennsylvania, citizens of the nited States, have invented or discoverednew and useful Improvements in Glass- Castmg Apparatus, of which the following is a s eciiication.

eferring fo the drawings, Figure 1 isa plan View, vpartly in horizontal section and partly broken away, showing our invention;

1g. 2, a side elevation of the same; Fig. 3, a

cross-section of the casting-bed and contiguous parts, showing the means employed to adjust the bed vertically; and Fig. 5, a view showing the removable collars for the rolls.

Our invention relates to mechanismior making sheets of glass by rolling a pouring of glass between one or more rolls and a casting- The objects of our invention are to provide a novel means for cooling the casting-bed, to make the bed in sections so that dama ed or undesirable parts may be chea ly rep aced, and to so construct the bed an its carria e that the former may be vertically adjustab e on the latter.

Further objects of our invention will a pear in the detailed description immediate y to follow. 4

We provide a pair of rails 1, forming a car 3, supporting thecas'ting-bed or table 4, travel bac and forth beneath the roll 5, the roll preferably carrying at each end a sectional collar 5a. This collar is made up 'of two arc-shaped sections which when united form an annulus or collar. The ends of the collar-sections are united by means of screws 5b, which pass through overlapping tongues of the joints. Said screws are shown as passthe heads countersunk inl the outer tongue ilush with the surface of the collar.

The casting-bed 4 has upper and lower sections 6, provided withexternal casting-surfaces 7, which may have different characteristics. For exam le, one surface may be smooth and the ot er ribbed or otherwise fig- The conan essential feature. .The two sections 6 of the bed 4 are fastened together by-bolts or screws 1.1. The bed is provided with end caps 12 and 13, each havin a hollow or groove which with the ends o the bed form common chambers 14, communicating with the ports 10 ofthe grooves 9.

15 15 are tubes for conveying water from the chamber 14 in the caps 12, and 16 16 are tubes for conveying water into the chamber' 14 in the caps 13. If desired, any other number of tubes 15 and 16 may be em loyed. In fact, the tubes may connect directly with the orts 10.

T e caps are secured tothe bed by bolts 17. Extendin outwardly from the face of each ca' 12 an 13 is a lug or journal 18, havingthe llead 19.

. The screws 20 are threaded into holes 21 in the iixed nuts 22, secured in the-sides of the car, and are preferably four in number, though a larger number maybe used. These screws bear at their upper ends against block 23, on which the bed 4 rests'. The screws 20in Fi 2 a pear far from the ends of the bed 4; ut t `s is because a large portion of the bed has been omitted between the wheels 2, as shown.

24 designates one of the journal-boxes for a v iop 27 and the journal-block 24. As these fea-I tures do not form any part of the present 111-.

vention, they need not be further described. ,Y

Thev carriage 3 is provided with lateral.

4 solely by adjusting the roll -space between the racks 33, with which mesl lthe pinions 34, 'fast on the end portions of -t'hefroll 5.

It is found. that When-it is attempted to regulate the thickness of the glass sheets 5 by means ol.' the screws 28 the pinions 34 and .racks 33 will fail to mesh when the sheets are made too thick; By making the adjustments wholly or in part by the operation of the screws the glass sheets may be made of any required thicknesswithout theiseparation of the racks and pinions. Furthermore, the screws provide convenient and reliable means for making the bed absolutely level. v

When the roll has been raised or the bed has been lowered to make adjustments for thicker or thinner sheets of glass, the collar 5"" previously in use is removed. and another onehaving the requisite thickness to iill the space between the roll'and the bed is substituted. therefor.- This is a particularly valuable feature, since the roll itself has on it the means for closing the end portions of the bed and that part of the rozltwhioh rolls the upper surface oi' the dass.

W hen it becomes ersirable to use the oWer casting-surface 7, hoisting devices, as the hooks of atraveling crane, are connected 'to the lugs 18 on the eastingpbed and. the latter raised above the carriage 3. The bed is then rotated, the hooks acting as journal-bearings for the lugs 18, and again lowered upon thev carriage. Q

i l I.; I/ l I- n Instead of raising 'the .bed high enough .above the car to allor the .-bed. to be rotated the bed may beslightly raised and the oar run out 'from beneath the same. The bed may then be rotated, the car returned, and the bed lowered upon/the ear. It would be possible also to lower the ear without raising the bed, so that the bed could be rotated or the oar removed from beneath it.

Having described our invention, We claim l. A fluid-cooled nesting-bed having contiguous sections so constructed that, when the sections are assembled open-ended parallel internal passages are thereby formed, channeled end sections bridging the ends of the passages, and inlet and outlet pipes connected respectively to the end sections.

2. ln a glass-casting apparatus, a castingbed having a plurality of separable external caStii'ig-surfas, a support therefor Vduring casting operations, and journals independent of the support, wbereon the bed may after a casting operation be supported. and rotated to bring a second casting-surface uppermost.
